Title: Eddy current flaw inspection and manufacture of reference sample therefor
Inventor: IMATAKI IKUO
IPC: G01N1/32
Filed: 1989-10-31
Abstract: PURPOSE:To accurately decide the internal flaw of an object to be inspected by comparing the reference flaw detection signal related to a reference sample having a know flaw and the actual flaw detection signal of the object to be inspected. CONSTITUTION:Two kinds of eddy current flaw detections are performed with respect to a reference sample 1A having a known flaw. At first, an inspection device 10 is adjusted to pass, for example, a current with frequency of 400kHz through a coil 12 and the coil is sent into a reference pipe 1A and the first flaw detection signal 21 outputted from the inspection apparatus 10 is obtained. Next, for example, a current with frequency of 200kHz is mixed with the current with frequency of 400kHz and both currents are allowed to pass through the coil 12 to obtain the second flaw detection signal 22. By mixing the flaw detection signals 21, 22 in a reverse phase, the third flaw detection signal 23 is synthesized to be set to an actual flaw detection signal 26. Next, the same operation is applied to a pipe 1 being an actual object to be inspected to obtain an actual flaw detection signal 36. By comparing the actual flaw detection signals 26, 36, the internal flaw of the pipe 1 can be decided accurately.

Abstract: PURPOSE:To easily identify the present moving locus of a new tool based on a past tool moving locus by changing the luminance level of the display data for each prescribed timing via a luminance level control means and displaying the display data according to said luminance level via a display means. CONSTITUTION:A display data memory means 33 stores the display data corresponding to the moving locus of a tool and the luminance level memory means 43a-43c store the luminance levels of the display data. A luminance control means 42 changes the luminance level for each prescribed timing and a display means 42 displays the display data according to the luminance level. These means form a display device for tool moving loci that is used by a numerical controller. In other words, the means 33 and 43a-43c store the display data and the luminance levels respectively together with the means 42 which changes the luminance level of the display data for each prescribed timing, and the means 41 which displays the display data based on luminance levels. Thus it is possible to easily identify the present new tool path from a past tool path while it is possible to read the movement of the past tool path.
